	  Decompress a block of compressed data and returns the size of the 
	  decompressed block. If error occurs, e.g. the compressed data is 
	  corrupted or the output buffer is not large enough, then 0 (zero) 
	  will be returned instead.
	
	  The input buffer and the output buffer can not overlap.
	
	  Decompression is memory safe and guaranteed not to write the output buffer
	  more than what is specified in maxout.

	  Compression level can be specified in parameter level. At the moment, 
	  only level 1 and level 2 are supported.
	  Level 1 is the fastest compression and generally useful for short data.
	  Level 2 is slightly slower but it gives better compression ratio.
	
	  Note that the compressed data, regardless of the level, can always be
	  decompressed using the function fastlz_decompress above.
